leaking seals on 4 WD

[BC Dave]

I have some weeping seals on on both sides of the front knuckle area on a 180D; are these easy to get at to replace? clean?

the seller said they just needed to be cleaned out ...

... is this a common problem? I noticed several seals in the parts diagram; which ones need to be cleaned / replaced?

Cheers a BC D

Never much heard of cleaning a seal. If you go that far I would recommend replacement. Don't know if yours is like the 1500 but #26 in the drawing is the knuckle seal. Yours would be similiar. Many people have had success with adding Lucas power steering stop leak. Just a thought. The seals are not difficult to change although I have never touched a ym180d.

If you have to take them out to clean them. I would install new ones. I doubt cleaning seals will stop leaking. New ones will if, bearings,etc are in good shape

 

[BC Dave]

yes; it would be wise to replace a waring part once you've gone to the trouble of taking it all appart ...

I had one leaking several months ago...from the advice here I tried the power steering stop seal leaking bottle and it has not leaked since.

Worth a shot.

Same thing here.....had some leakage on my 186D......added Lucas Power Steering Stop Leak......problem solved. I'd try it before tearing it apart. :thumbsup:

stop leak; Its an idea; but I also wonder if the stop leak would gum up the oil or other parts ...

alot of the tractors we brought in that were 4wd ie, the 1500D's had the front axles grease packed. I cleaned them and replaced any needed parts (mostly seals etc..), but in retrospect, having the front end packed with a high quality synthetic or moly grease could lubricate just as well.

If your talking about what I'm thinking it is quite a thing to fix. Lucky I was able to locate a seal at John Deere but i know that all of the parts are not easily obtained for the front axle. Mine leaked a lot on our garage floor (concrete) and since I did not want to stain the floor I just decided to fix the leak at hand. If you do go ahead and fix it you should take your time, I spent a good 4 days working on it for about 2-3 hour intervals and since I had to locate some parts which turned weren't available so I had to use the old ones. Good luck on the fix!

I respectfully disagree that grease is as good a lubricant in these 4 wheel drive trains. Grease will tend to permanently locate in the cavities and you will lose lubrication in places. You will notice on finish mowers they recommend lubricating the spindles every 8 hours or so depending on manufacturer. Reason is to move that grease on through. I don't think you will find any manufacturer of front wheel drives recommending grease as a lubricant. This is "my opinion".
